It seems to be neither a "User Prefs" problem, nor a volume read problem. The error travels with the folder, not with Preferences. Command-option launching PowerMail and checking all the boxes to rebuild everything returns the same Error -199.
I have: DriveSTUP/~/Mail/PowerMail Files/ DriveBKUP/~/Mail/PowerMail Files/ DriveSTUP is my Startup drive. DriveBKUP is a backup that is 1 week old. PowerMail opens the one on DriveBKUP OK, whether I start up from either drive. PowerMail throws an Error -199 when I try to open the one on DriveSTUP, whether I start up from either drive. PowerMail throws an Error -199 when copy the problem mail folder from DriveSTUP to any other rdrive, including DriveBKP. If something is corrupt, what is it? Is there any way to recover that database?
